In this type, the axial reciprocating motion of the pistons is obtained by a swash plate that is either fixed or variable in its degree…

As the name implies, these pumps discharge a fixed quantity of oil per revolution of the pump shaft. In other words, they produce flow proportional…
They are also known as hydro-dynamic pumps. In these pumps the pressure produced, is proportional to the rotor speed. In other words, the fluid is…
The sole purpose of a pump in a hydraulic system is to provide flow. A pump, which is the heart of a hydraulic system, converts…
A variable displacement pump is more expensive, but it adds tremendous options for the design of a fluid power circuit. A servo valve can be…
Radial piston motors produce very high torque at low speed. They are used as wheel motors for large equipment. Pistons operate in radial bores in…
The piston shaft (tapered section shown in Fig. 5.15) does not provide the linkage that ensures that the cylinder block rotates with the output shaft.…
Bent axis motors were developed to improve the operating and stall torque efficiencies of high-speed motors. The design (Fig. 5.15) operates in a manner similar…
The Vickers Model MHT50 vane motor with 38 in3/rev maximum displacement was chosen for an example. This motor is rated for a maximum pressure of…
The Char-Lynn 10,000 series motor with 40.6 in3/rev displacement was chosen for an example. (Notice that this displacement is approximately 10 times the displacement of…
